Implantable pacemaker using thermoelectric power generation

Abstract

The invention relates to an implantable pacemaker utilizing temperature difference to generate power, which belongs to the technical field of medical instruments and comprises a plug-in body, a shell, a communication piece, a heat conduction piece and a circuit board. The shell accommodates the communication piece, the heat conduction piece and the circuit board, and the front and rear surfaces are provided with protrusions and recesses, so that the contact area with human tissues is increased, and the temperature difference between the front and rear surfaces is increased. The shell sequentially comprises a shielding layer, a thermoelectric layer and an electricity storage layer from outside to inside. The thermoelectric layer and the shielding layer are fixedly connected and insulated, and can generate power by using temperature difference to supply power to and charge the pacemaker, so that the service life is prolonged; the electricity storage layer and the thermoelectric layer are fixedly connected and insulated, and can store electric energy, charge and supply power to the pacemaker, the mass is reduced, and the space is saved. The heat conduction piece penetrates through the circuit board, abuts against and is attached to the inner side surface of the protruding portion of the shell on the front side face and the rear side face of the circuit board, penetrates through the electricity storage layer and abuts against and is attached to the thermoelectric layer, heat conduction can be achieved, the thermoelectric layer can generate electricity conveniently through temperature difference, and the electricity generation power and efficiency are improved.

Description

technical field [0001] The invention relates to a pacemaker, in particular to an implantable pacemaker, and belongs to the technical field of medical devices. Background technique [0002] Implantable pacemakers need to be surgically implanted under the skin, and the common ones are cardiac pacemakers and brain pacemakers. A pacemaker includes a circuit and a battery encapsulated in an airtight case, and is the core component of the pacing system; the pacing system also includes electrode leads and a programmer. [0003] Implantable pacemakers require batteries to provide electrical energy, generate electrical pulses, and have a certain lifespan; their replacement requires surgery, which increases the pain of patients, has high risks and high costs. In order to improve lifespan and supplement energy, a variety of technical solutions have emerged. For example, the utility model patent with the application number of 201820277430.1 discloses a new type of cardiac pacemaker th...
